BIRD SPECIES ON LEGON CAMPUS BY MARK KWASI ACHEAMPONG (10221154) THIS THESIS IS SUBMITTED TO THE UNIVERSITY OF GHANA, LEGON IN PARTIAL FULFILLMENT OF THE REQUIREMENT FOR THE AWARD OF MPHIL ZOOLOGY DEGREE JULY, 2013 . Basal areas and volumes were at least 49% lower than national means for same forest zone. Shea (Vitellaria paradoxa C.F. Ghana's closed forests contain over 2100 plant species, most of the 818 tree species which have been identified in Ghana, and certain endangered and endemic species (19 species and two subspecies; IUCN, 1988). The study took place at Kakum Conservation Area, Ghana. We used species presence/absence data from 2505 1-ha plots systematically distributed over Ghana's forests. Aim To quantify the influences of forest area, shape and isolation on tree species diversity in Ghana and to compare their significance with the influences of climate (average annual rainfall) and disturbance (fire burn, logging, agriculture). For all sample trees, volume of the main stem, wood density, wood carbon (C) concentration and C content were determined. Perrier’s Baobab, Adansonia perrieri, is found in the northern part of Antsiranana in Madagascar. Therefore models that predict merchantable volume from stump. All trees are Vascular plants. The study took place at Kakum Conservation Area, Ghana. Of the mammal species in Ghana, five are endangered, eleven are vulnerable, ... Tree pangolin, Manis tricuspis LR/lc; Order: Cetacea (whales) The order Cetacea includes whales, dolphins and porpoises. (N/A) Project No. To assess the role of water availability in shaping species distribution, we carried out a reciprocal transplanting experiment in gaps in a dry and a wet forest site in Ghana, using 2,670 seedlings of 23 tree species belonging to three contrasting rainfall distributions groups (dry species, ubiquitous species, and wet species). Other Cooperating Institutions Project Status. The fauna of the Ghanaian terrestrial ecosystem, comprise a diverse array of species including several of conservation concern. One distinctive endemic species is the Mount Nimba toad ( Nimbaphrynoides occidentalis, CR), which gives birth to fully developed toadlets after a gestation period of nine months. In total 44 tree species (831 individuals belonging to 25 families) were found per 40 ha. Logistic regression was used to determine species responses to four climatic variables generated from the Worldclim database. Logistic regression was used to determine species responses to four climatic variables generated from the Worldclim database. KEYWORDS: Tree species, neem, cassia, teak, Ghana INTRODUCTION Like many countries in sub-Saharan Africa, Ghana’s bulk energy supply for heating and cooking is from woodfuel, in the form of firewood and charcoal (Ghana Statistical Services, 2014). Objective: Stand structure, composition, abundance and diversity of tree species of the northern forest-savanna ecotone were characterized to determine their spatial variability for land management.Methodology and result: An inventory of the in-situ tree community of the northern forest-savanna ecotone of Ghana was undertaken using the stratified random sampling technique. The herb/shrub species, Chromolaena odorata is identified as a primary factor for the difficulties of tree recruitment. The neem tree (Azadirachta indica), also known as the Indian lilac or margosa tree, is one of Ghana's more useful native plants. Tree; A tree is defined as a perennial woody plant with roots, having a single stem (trunk) with branches extending out from the sides and top of this trunk, forming a distinct elevated crown. According to Oteng-Amoako et al. The species is distributed over the tropical areas of West Africa and Central Africa.. Ficus platyphylla, Mangifera indica, Polyalthia longifolia and Terminalia catappa, which were abundant and well distributed along the road sides, were selected for the study. tree species in Ghana (TEDB, 1994). Many additional species are likely to be discovered; for example, 11 new frog species have been discovered in the last decade alone. Triplochiton scleroxylon is a tree of the genus Triplochiton of the family Malvaceae.The timber is known by the common names African whitewood, abachi, obeche (in Nigeria), wawa (in Ghana), ayous (in Cameroon) and sambawawa (in Ivory Coast).. We used species presence/ absence data from 2505 1-ha plots systematically distributed over Ghana's forests. This is a list of the mammal species recorded in Ghana. We evaluated the relative importance of annual rainfall, temperature and their seasonality to tree species distribution in Ghana. We used species presence/absence data from 2505 1-ha plots systematically distributed over Ghana's forests. Abstract: We evaluated the relative importance of annual rainfall, temperature and their seasonality to tree species distribution in Ghana. The fibres are exported to many other countries. Accession No. Over 360 tree species have been recorded of which about 190 grow to timber size. Highlights A study of tree population structure in a deciduous forest in Ghana lacking previous inventory data. Reporting Frequency. Apr 1, 2004 Project End Date. Its leaves are a source of food to most people while the dried fruit pulp is a food ingredient. Sponsoring Institution. A multipurpose tree that is very important for the local population, supplying food, fibres and building materials. Stakeholders in the wood and timber industry have held a training workshop to dialogue on the promotion and use of Lesser-Known timber species in Ghana and for export. It has a very straight stem and dark gray bark. Description. Almost 126 of them occur in sufficient volumes to be considered exploitable as raw material base for the timber industry (Ghartey, 1989). most tree species have complex buttresses, estimation of tree volume from stump diameter may not be accurate. Perrier's baobab. 23 tree species belonging to three contrasting rainfall distributions groups (dry spe-cies, ubiquitous species, and wet species). Well-known for the insect-repellent properties of its oil, the neem tree is widespread in Ghana, where it grows to heights of up to 66 feet. (N/A) Program Code (N/A) Project Start Date.

(N/A) Multistate No. Diversity indices show poorly diverse forest with 50% of the area dominated by five species. It is clear the hotspot supports a high diversity of tree frogs. Raphia vinifera, the West African piassava palm, bamboo palm or West African bass fibre is a palm tree species. This study investigated factors affecting the carbon content of nineteen tropical plantation tree species of ages seven to twelve and compared carbon content of Khaya species from two ecozones in Ghana. i DECLARATION I hereby declare that except for references to other peoples’ work which have been duly cited, this thesis is entirely my original work … Annual. Dec 31, 2007 Grant Year (N/A) Project Director … We evaluated the relative importance of annual rainfall, temperature and their seasonality to tree species distribution in Ghana. The economic value of Ghana's forest resources lies in the revenues derived mainly from exploitation of its wealth of commercial timbers and the considerable volume of commercial woods and other non-timber forest products (NTFPs). Shade tree species richness, Shannon, Simpson’s reciprocal and Margalef diversity indices were estimated from 84 organic and conventional cocoa agroforestry plots. The tree produces white, slightly fragrant flowers. Find here the different species of timber available from Ghana Forestry Commission. 5. 0203056 Grant No. An investigation was conducted to evaluate the impact of vehicular air pollutants on some selected roadside tree species in the Kumasi Metropolis, Ghana. Logistic regression was used to determine species responses to four climatic variables generated from the Worldclim database. Trees in quadrats that were systematically distributed on transects were enumerated. We evaluated seasonal patterns in climatic conditions, seedling physiology and performance (survival and growth) over a 2-year period and related seedling performance to species distribution along Ghana’s rain- It is particularly abundant along the creeks of Niger Delta, Cross River, Lagos and Ikorodu in Nigeria. Predicting stumpage volume of commercial species in Ghana 3 diameter may not be reliable for most tropical tree species. Trees can be either evergreen, deciduous or semi-evergreen, and either type may have leaves or needles. 4.6% of Ghana is protected under IUCN categories I-V. 2011 Update In May 2011, Sassan Saatchi of Caltech's Jet Propulsion Lab and colleagues published a paper in PNAS … directly affected by the economic situation. Approximately 420 of these tree species attain timber size and therefore are of potential economic value (Hall and Swaine 1981).
